US President Donald Trump is considering sending long-range Tomahawk cruise missiles to Ukraine.

Asked by reporters on Air Force One on Sunday whether he would provide Kyiv with Tomahawks, Trump replied: We'll see... I may. The missiles, if sent, would mark a new step of aggression in Ukraine's ongoing war with Russia.

His remarks came following a phone call with Ukrainian President Volodymyr Zelensky over the weekend, who urged for enhanced military capabilities to launch counter-attacks against Russian forces.

The prospect of the US supplying long-range missiles has drawn sharp warnings from Moscow, signifying a potential escalation in an already tense conflict and further straining US-Russian relations.

Tomahawk missiles, with a striking range of 2,500 km (1,500 miles), could enable Ukraine to target deep within Russian territory. Trump mentioned he may discuss the missile situation with Russian officials, suggesting that such a move would be unlikely to sit well with the Kremlin.

Kremlin spokesman Dmitry Peskov expressed extreme concern regarding the potential of missile supplies to Ukraine, indicating that escalation from both sides is imminent.

Former Russian President Dmitry Medvedev reacted to the missile talk, warning of dire consequences for Trump and the broader geopolitical landscape, emphasizing that such military actions could end badly for all involved.

The discussions between Trump and Zelensky included comprehensive talks about bolstering Ukraine's military capabilities amidst ongoing attacks on its cities, especially as winter approaches.
